If you access the Internet via a single ISP, press this link. 
 
ISP Name 
Enter your ISP name.   
Dial Number 
Enter the ISDN access number provided by your ISP.   
Username 
Enter the username provided by your ISP.   
Password 
Enter the password provided by your ISP. 
Require ISP Callback 
(CBCP)
 
If your ISP supports the callback function, check this box to 
activate the Callback Control Protocol during the PPP negotiation. 
Scheduler (1-15) 
Enter the index of schedule profiles to control the Internet access 
according to the preconfigured schedules. 
Link Type 
There are four link types: Link Disable, Dialup 64 Kbps, Dialup 
128 Kbps, and Dialup BOD.   
Link Disable - Disable the ISDN dial-out function. 
Dialup 64Kbps - Use one ISDN B channel for Internet access. 
Dialup 128Kbps - Use both ISDN B channels for Internet access. 
Dialup BOD - BOD stands for bandwidth-on-demand. The router 
will use only one B channel in low traffic situations. Once the 
single B channel bandwidth is fully used, the other B channel will 
be activated automatically through the dialup. For more detailed 
BOD parameter settings, please refer to the Advanced Setup field 
Call Control and PPP/MP Setup.  
PPP Authentication   
PAP Only - Configure the PPP session to use the PAP protocol to 
negotiate the username and password with the ISP.   
PAP or CHAP - Configure the PPP session to use the PAP or 
CHAP protocols to negotiate the username and password with the 
ISP.  
Idle Timeout 
Idle timeout means the router will be disconnect after being idle for 
a preset amount of time. The default is 180 seconds. If you set the 
time to 0, the ISDN connection to the ISP will always remain on.   
Fixed IP 
In most environments, you should not change these settings as 
most ISPs provide a dynamic IP address for the router when it 
connects to the ISP. If your ISP provides a fixed IP address, check
